Abstract

PCT No. PCT/GB92/01180 Sec. 371 Date Dec. 30, 1993 Sec. 102(e) Date Dec. 30, 1993 PCT Filed Jun. 30, 1992 PCT Pub. No. WO93/01242 PCT Pub. Date Jan. 21, 1993.An article intended to be degraded when exposed to the environment is made from a brittle resinous or synthetic resin material incorporating moisture swellable particles as a filler, whereby exposure of the article to water induces fragmentation. In particular, hydrodegradable "clay pigeons" for shot-gun shooting may be made from a mixture of pitch, powdered limestone or chalk and dry potato starch. Exposure of such a "clay pigeon" or fragments thereof, to water causes swelling of the starch particles and consequent fragmentation of material into, eventually, a fine sludge which is ultimately absorbed into the ground.
